Title: Two-point support structure for piezoelectric oscillating chip
Inventor: IKEDA TATSUO
IPC: H03H9/02
Filed: 1985-04-30
Abstract: PURPOSE:To improve the temperature characteristic and the shock resistance and to attain thin profile by using a lead wire having a spiral part surrounding a piezoelectric oscillating chip. CONSTITUTION:An electrode pattern 2 is formed to the front and rear side of a rectangular AT crystal oscillating chip 1. Further, lead wires 6, 6' are fixed to a holder 4 by glass 5 and the spiral part surrounds the oscillating chip 1. The oscillating chip 1 is fixed on the lead wires 6, 6' by a conductive adhesives 3. Since the length of the lead wire from the fixed part of the holder and the lead wire to the fixed piezoelectric oscillating chip is made longer, the temperature characteristic and the shock resistance are improved. Further, the height of the leads wire is kept lower, thin profile is attained.

Title: Magnet catch attached with shaking detection means
Inventor: HASHIZUME HIROKO
IPC: E05C17/56
Filed: 1995-03-14
Abstract: PURPOSE:To prevent a hinged-door from opening by attaching to a magnet a shaking detection means which is movably supported by a shaking force when an earthquake is generated and which moves up to an opening inhibition position of the hinged-door. CONSTITUTION:When an earthquake is generated, a spring means 1 is vibrated. When the vibration reaches a magnitude which exceeds a definite value, a magnet 2 is attracted by a main body side-fitting 4. Then, a projected member 8 is fitted into a hole which serves as a locking means 7 of an object side-fitting 6 so as to lock. Even when hinged-doors 61 and 62 fail to resist against the force of the earthquake with an attracting force of a magnet catch 40 and forced to be opened, the lock of the projected member 8 prevents the doors from being opened. In case when the lock is released, if an operation piece 51 is turned, the lower end of a release piece 53 will come into contact with the portion attracted by the fitting 4 on the upper end of the magnet 2. If the operation piece 51 is further turned, the release piece 53 will separate the magnet 2 from the fitting 4 to which the magnet 2 is attracted, thereby releasing the lock. This construction makes it possible to prevent the doors from being opened during an earthquake and simplify the structure of the doors and mount them easily as well.
